Description

Steam pipe structure of an anti-tipping and leak-proof electric kettle Technical Field

[0001] This utility model relates to the field of electric kettle technology, and more specifically to the steam pipe structure of an anti-tipping and leaking electric kettle. Background Technology

[0002] Currently, electric kettles on the market consist of a kettle body, a lid, a steam pipe, and a thermostat. The steam pipe is located on the side wall of the kettle body, with its top end connected to the inner cavity of the kettle and its bottom end connected to the thermostat. During the boiling process, the water produces a large amount of steam, which enters the steam pipe and flows down to the thermostat. When the temperature-sensing metal spring on the thermostat senses that the steam temperature has reached the preset value, the metal spring deforms due to heat, thus automatically shutting off the kettle. However, if the kettle body is tilted or tipped over, or if the user is accidentally tripped, a large amount of boiling hot water will gush out from the steam pipe, which can easily scald the user and cause injury. It can also wet the base, causing an electrical short circuit and potentially leading to electric shock.

[0003] Therefore, in order to solve the problems existing in the prior art, the applicant proposes the following technical solution. Technical solutions

[0004] In view of this, the present invention provides a steam pipe structure for an anti-tipping and leaking electric kettle.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a steam pipe structure for an anti-tipping and leaking electric kettle. The kettle body is equipped with a spout and a handle, which are symmetrically arranged. A steam pipe is installed inside the kettle cavity, comprising a coil section and an extension section. The coil section is located at a high position in the kettle cavity and coils along the inner wall of the cavity. The upper end of the extension section is connected to the coil section, and the lower end of the extension section extends downward to the bottom of the kettle cavity. An upper steam inlet is provided at the beginning of the coil section, and a lower steam outlet is provided at the lower end of the extension section. The bottom of the kettle cavity has a center point O. The upper steam outlet forms a projection point A at the bottom of the kettle cavity, and the lower steam outlet forms a projection point B at the bottom of the kettle cavity. In the coiling direction of the coil section, the angle ∠AOB is α, and α ≥ 180°. The projection of the connecting line between the spout and the handle at the bottom of the kettle cavity is the connecting axis L, and the projection point B of the lower steam outlet is not on the connecting axis L. This technology, by limiting the positions of the upper steam inlet and lower steam outlet of the steam pipe, ensures that no matter how the electric kettle is tilted or tipped over, one end of the upper steam inlet and lower steam outlet is always above the liquid surface, or a section of the steam pipe is above the liquid surface. This prevents a large amount of boiling hot water from gushing out of the steam pipe at once, thus preventing injury from excessive hot water gushing out of the steam pipe and preventing excessive water from wetting the base, causing electrical short circuits and electric shocks, thereby improving safety.

[0006] As a preferred embodiment of this utility model, the coil section is coiled around the inner wall of the kettle cavity at least once. In this case, no matter how the electric kettle is tilted or tipped over, at least one section of the coil section will remain above the liquid surface, and the water cannot overcome gravity and flow upwards, thus preventing the boiling hot water from gushing out of the steam pipe in large quantities and causing injury.

[0007] As a preferred embodiment of this utility model, the coil section is coiled around the inner wall of the kettle cavity less than once, reducing the length of the coil section and saving materials. At the same time, it can ensure that no matter how the electric kettle is tilted or tipped over, one end of the upper steam inlet and the lower steam outlet of the steam pipe is always above the liquid surface; or a section of the steam pipe is always above the liquid surface.

[0008] As a preferred embodiment of this utility model, the projection point B of the lower steam outlet is close to the handle; the projection point A of the upper steam outlet is close to the water outlet; the layout is reasonable and makes it easier to connect the lower steam outlet to the steam box.

[0009] As a preferred embodiment of this utility model, the extension section extends out of the bottom of the kettle cavity and connects to the steam box. The steam box is connected to a temperature control switch, so that the temperature control switch can normally sense the temperature and trip.

[0010] In a preferred embodiment of this utility model, the extension section extends from the high position to the low position of the pot cavity, and the extension section is set in a straight line or a curve.

[0011] As a preferred embodiment of this utility model, the upper steam inlet is positioned higher than the highest water level in the kettle cavity, ensuring that the upper steam inlet is higher than the liquid level when the electric kettle is placed vertically. Beneficial effects

The best embodiment of the present invention

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0028] For the steam pipe structure of the anti-tipping and leaking electric kettle, please refer to Figure 1-5. The kettle body 100 is provided with a spout 110 and a handle 120. The spout 110 and handle 120 are symmetrically arranged so that when the electric kettle is lifted by the handle 120, the handle 120 tilts upward and the spout 110 tilts downward to pour water.

[0029] As shown in Figure 1, the body 100 is set in an arc-shaped barrel, the spout 110 is set as a gooseneck spout, the body 100 forms a water storage cavity 01, the top of the body 100 is the spout, and a lid is installed at the spout.

[0030] The bottom of the pot cavity 01 is a base plate 130, and a base 140 is provided below the base plate 130. A cavity for assembling heating elements and other components is formed between the base plate 130 and the base 140.

[0031] A steam pipe 200 is installed inside the kettle cavity 01. The steam pipe 200 includes a coil section 210 and an extension section 220. The coil section 210 is located at the high position of the kettle cavity 01 and is coiled along the inner wall of the kettle cavity 01. The upper end of the extension section 220 is connected to the coil section 210, and the lower end of the extension section 220 extends downward to the bottom of the kettle cavity 01, that is, it extends downward through the base plate 130. The steam pipe 200 is generally made of metal pipe and is formed by bending the metal pipe. In Figure 1, the kettle body 100 is arc-shaped and the inner wall of the kettle cavity 01 is arc-shaped. Therefore, the coil section 210 is arc-shaped and coiled around the inner wall of the kettle cavity 01. The upper steam inlet 201 is provided at the beginning of the coil section 210, and the lower steam outlet 202 is provided at the lower end of the extension section 220.

[0032] As shown in Figure 3, from a top view, there is a center point O at the bottom of the kettle cavity 01. The upper steam outlet 201 forms a projection point A at the bottom of the kettle cavity 01, and the lower steam outlet 202 forms a projection point B at the bottom of the kettle cavity 01. In the coiling direction of the coil section 210, the angle of ∠AOB is α, and α≥180°.

[0033] Here, the coiling direction of the coil section 210 is the direction in which the upper steam inlet 201 extends, which is the coiling direction, i.e., the counterclockwise direction in Figure 3.

[0034] As shown in Figure 3, the projection of the connecting line between the spout 110 and the handle 120 onto the bottom of the kettle cavity 01 is the connecting axis L, and the projection point B of the lower steam outlet 202 is not on the connecting axis L.

[0035] In one embodiment, the upper steam inlet 201 is positioned above the highest water level line in the kettle cavity 01, ensuring that the upper steam inlet 201 is also above the liquid surface when boiling water.

[0036] In one embodiment, the coil section 210 is coiled around the inner wall of the kettle cavity 01 at least once, or the coil section 210 is provided with multiple coils. With multiple coils, when the kettle cavity 01 is under rated water volume, after the electric kettle is tilted or tipped over, at least one section of the coil section 210 is kept above the liquid surface. Hot water cannot overcome gravity and flow backwards to the section above the liquid surface, so that boiling hot water will not gush out from the steam pipe in large quantities instantly, making it safer to use.

[0037] In one embodiment, the coil section 210 is coiled around the inner wall of the pot cavity 01 less than one turn, as shown in Figure 3. The coil length of the coil section 210 in Figure 3 is less than one turn, which can effectively save materials and meets the requirement that the angle of ∠AOB is α, α≥180°.

[0038] As shown in Figure 6-11, when the coil length of the coil section 210 is less than one turn, when the electric kettle is tilted, because the kettle body 100 is equipped with a spout 110 and a handle 120, due to the lever principle, the electric kettle will always keep the handle 120 side facing down or the spout 110 side facing down when tilted, or maintain balance.

[0039] As shown in Figure 6, after the electric kettle is tilted, the spout 110 faces the upper left and the handle 120 faces the lower right and is in contact with the ground. At this time, a part of the coil section 210 is above the liquid surface, while the lower steam outlet 202 is below the liquid surface and the upper steam inlet 201 is above the liquid surface. The boiling hot water cannot flow out from the steam pipe 200.

[0040] As shown in Figure 7, after the electric kettle is tilted, the spout 110 faces the lower left and is in contact with the ground, and the handle 120 faces the upper right. At this time, a part of the coil section 210 is above the liquid surface, while the lower steam outlet 202 is below the liquid surface and the upper steam inlet 201 is above the liquid surface. The boiling hot water cannot gush out from the steam pipe 200.

[0041] As shown in Figure 8, when the electric kettle is tilted, the spout 110 faces the upper right and the handle 120 faces the lower left and is in contact with the ground. At this time, the lower steam outlet 202 is above the liquid surface and the upper steam inlet 201 is below the liquid surface, so the boiling hot water cannot gush out from the steam pipe 200.

[0042] As shown in Figure 9, when the electric kettle is tilted, the spout 110 faces the lower right and is in contact with the ground, and the handle 120 faces the upper left. At this time, the lower steam outlet 202 is above the liquid surface, and the upper steam inlet 201 is below the liquid surface. The boiling hot water cannot gush out from the steam pipe 200.

[0043] As shown in Figure 10, when the electric kettle is tilted, the spout 110 is horizontally facing to the right and the handle 120 is horizontally facing to the left. At this time, the lower steam outlet 202 is above the liquid surface and the upper steam inlet 201 is below the liquid surface, so the boiling hot water cannot gush out from the steam pipe 200.

[0044] As shown in Figure 11, when the electric kettle is tilted, the spout 110 is horizontally facing to the left and the handle 120 is horizontally facing to the right. At this time, the lower steam outlet 202 is below the liquid surface and the upper steam inlet 201 is above the liquid surface, so the boiling hot water cannot gush out from the steam pipe 200.

[0045] In all six tilting scenarios described above, the electric kettle can maintain either the upper steam inlet 201 or the lower steam outlet 202 above the liquid surface, or keep a section of the steam pipe above the liquid surface, ensuring that boiling hot water cannot gushed out from the steam pipe 200 and ensuring product safety.

[0046] In addition, it is worth noting that in the above six tilting situations, the water volume in the kettle cavity 01 must not exceed the rated water volume; while the specific rated water volume in the kettle body 01 is related to the size of the kettle body 01, and the rated water volume is determined through testing.

[0047] In addition, apart from the six tilting situations mentioned above, it is almost impossible for the lid to be facing down and the bottom of the pot to be tilted up. Even if this situation exists, it ensures that the lower steam outlet 202 is higher than the liquid level.

[0048] In one embodiment, the projection point B of the lower steam outlet 202 is close to the handle 120; the projection point A of the upper steam outlet 201 is close to the water outlet 110.

[0049] Furthermore, the extension section 220 extends out of the bottom of the kettle cavity 01 and connects to the steam box 300, which is connected to a temperature control switch 400;

[0050] Generally, a temperature control switch 400 is provided on the electric kettle base 140, and the temperature control switch 400 is located below the handle 120. The steam box 300 is located close to the temperature control switch 400. Therefore, the projection point B of the lower steam outlet 202 is close to the handle 120 side, which facilitates the layout of the product components. Correspondingly, the projection point A of the upper steam outlet 201 is close to the spout 110 side.

[0051] In one embodiment, the extension segment 200 extends from the high position to the low position of the pot cavity 01, and the extension segment 200 is set in a straight line or a curve; as shown in Figures 4-5, the extension segment 200 extends from top to bottom and is set with a slight arc.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
